Is it possible that your Inline::C is installed using a different compiler from the one used to compile Perl?

No, I've compiled 5.14 myself on this same machine, so the same compiler was used to build the whole setup. But that maybe indeed the problem : maybe I'm running the original system perl? I'll double check and retry.

When putting a smiley right before a closing parenthesis, do you:

Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
